     21 # SYNOPSIS:
     22 # netns_breakns.sh <NS_EXEC_PROGRAM> <IP_VERSION> <COMM_TYPE>
     23 #
     24 # OPTIONS:
     25 #	* NS_EXEC_PROGRAM (ns_exec|ip)
     26 #		Program which will be used to enter and run other commands
     27 #		inside a network namespace.
     28 #	* IP_VERSION (ipv4|ipv6)
     29 #		Version of IP. (ipv4|ipv6)
     30 #	* COMM_TYPE (netlink|ioctl)
     31 #		Communication type between kernel and user space
     32 #		for basic setup: enabling and assigning IP addresses
     33 #		to the virtual ethernet devices. (Uses 'ip' command for netlink
     34 #		and 'ifconfig' for ioctl.)
     35 #
     36 # Tests communication with ip (uses netlink) and ifconfig (uses ioctl)
     37 # over a device which is not visible from the current network namespace.
     38 #
     39 # There are two test cases which are trying to set an ip address on the veth1
     40 # device which is not inside the network namespace referred to by NS_HANDLE0:
     41 # 1. using netlink (ip command).
     42 # 2. using ioctl (ifconfig command).
